Gluten-Free Halloween Monster Whoopie Pies


It’s that time of year, guys and gals.  It’s about one month until Halloween which means it’s non-stop decorations and treats until the end of the year.  We could all use the extra cheer this year though, right?  Who knows what Halloween is really going to look like this year.  What I DO know is that our family is dressing up in classic costumes this year (vampire, witch, ghost) whether or not Trick-Or-Treating happens, and we will also watching all the scary movies and baking all the festive treats. 

I have to credit my four year old for coming up with the concept of these cookies, which are really more like whoopie pies, so let’s call them mini whoopie pies.  They are grain free, gluten-free but they don’t taste healthy whatsoever, ha!  They do call for sugar, but you could probably swap for stevia or monkfruit sweetener without any issue to make them sugar-free.  

Try these

  • 5 tbsp melted butter
  • 3 tsp honey
  • 1 egg, room temperature

Whoopie Frosting

  • 4 tbsp butter, softened
  • 1 cup powdered sugar (put granulated sugar or sugar substitute in blender to make powdered sugar)

  • Place in preheated oven for 10 minutes.
  • Let whoopies cool completely before adding the frosting
  • Mix softened better in an hand mixer or standing mixer until fluffy. Add in the powdered sugar, vanilla, and milk and mix until blended.

  • Spread frosting with a knife (or piping bag) on each half the whoopie, and add another whoopie on top.
  • Keep whoopies in fridge as frosting will soften at room temperature.
